有没有从事法拉第旋转片研究的？

现在光通信中无源器件在国内的生产越来越大。原料国产化很重要，像自聚焦透镜国产的逐渐增加，是否有人考虑法拉第旋转片？请相互交流

相当于单向光阀吧

法拉第旋转片的旋转角度和磁场强度有关，如果磁场强度过大，其旋转角度是否有个极限值？

There are two kinds of Faraday Rotator: one is crystal(e.g., TGG) which has a Verdat Constant and the rotation is the integration of v*B*dl. Another kind is magnetic Garnet, there is a critical value of magnetic field for saturation and the rotation depends on the thickness.

flux: what do you think?

Nanxin:

另发给你一封邮件了。

Flux: As faraday introduced, the Faraday Glass is another Faraday rotator, but I’’m not sure the Vendat cons is big enough at 1550nm. I’’ll need to discuss the spec of this kind od glass with faraday.
